Abstract:
I will present the initial result from a Spitzer GO-1
program to obtain mid-IR spectra of infrared luminous
galaxies, selected at z > 1. The mid-IR spectral features,
such as PAH emission and silicate absorption, have been
detected in ULIRGs at z ~ 1 - 2. The implication of this
study will be discussed.
